Ancient Acushnet - Titleist Pitching Wedge loft question and ID

I found an old Acushnet-Titleist PW when helping someone move.   It has about the same head shape as a Vokey 48.  The top of the iron says "Acushnet" and the middle has the Titleist logo with a golf ball in a circle.  I'm guessing it is about 52* or so because I have an SM4 54-11 bent 1* strong and they both hit about the same distance. It is a forged club and there is no ridge on the bottom (similar to that of an X31).   My guess it is a pre-1970 club.  I was going to donate it to Goodwill but it pitches nicely and is good for practice plus it could be a collector's item.

Here's a photo of a set of vintage Titleist clubs with this particular wedge as part of the set.
